No power to fuel pump.

Keep in mind this car was completely disassembled and going back together. 90% complete.
Key on. Gas gauge gets pinned to over full.
Test light with fuel pump jumped on test connection .
NO POWER to: the pump connector. Solid copper wire in trunk. Not even at the copper wire connector at the fuse block.
Changed relay.
Fuse is good.
What am I missing?

I have seen the ecm pin in the plug in part break off and lose voltage, remove the connectors and make sure all pins look good. I believe it is one near the corner of the connector.

Will do. I already had to repair one connection, I bought a harness off the for sale section and it looked much better than my previous but you never know what other people do......

Found the problem C100 bulkhead connector off engine harness. I tugged on the gray wire (fuel pump power feed) and it came right out. Then found two more....
